I have to admit this is a question I would not expect on any CUV forum. What does it matter what the top speed is? If you plan on approaching it in a CUV then you need some education on car dynamics and why it is a risk not worth taking if you plan to explore this limit. There are a select few CUVs that have been designed for 100+mph. I'm thinking along the lines of the Porsche Cayenne or Lambo Urus. I leave my high speed hijinks to my Mustang.

 

3.6 LFX V6 is same as Camaro V6 of the same year, add 20” Camaro rims with Z speed rated tires, and voila, an SUV Camaro 🤔😉

...think Mustang Mach-E... 🤦‍♂️

 

You are forgetting the center of gravity and mass. A Nox on camaro wheels does not make a car that should be going 130+ as the camaro is capable of. It is one thing to be able to reach those speeds but another to be safe doing it.
Don't get me started on the Mach-E. Would be fine it it was 1500 lbs lighter and had better rubber but has neither of those two things. The CG should be fine though with the heavy battery down in the floor but controlling that weight will always be a problem.

 

...my post was in jest...I’ve actually had both cars in my signature up to 130 MPH...both are scary at those speeds! I didn’t think either one was more stable than the other...you would think my much lower Z28 would be more stable, but the air still gets under it at those speeds and makes it feel light on its feat...and before anyone says anything, yes, both cars have been on the race track...yes, even the Equinox...

 

Just learning the v6 has over 300hp Wow

 

That was my reaction...when I was just kinda looking at Equinox’s in late ‘14, I stumbled on that fact, then there was never any doubt which motor I was getting! I didn’t even know about the problems with the 4 cylinders, I just wanted the 300+ HP! After I got on this forum and saw all the issues the 4’s were having, just another reason I’m glad I went with the 6!

 

Yea seriously what a sleeper

 

Yea I bet every time that kid tells that story he's going to say your car looked like this.

 

I've run mine for two hours at 100 MPH a couple of times, and it's non-dramatic (aside for constantly looking out for law enforcement). GM's tire choice limits the vehicle to 118 MPH or 190 KPH. I suspect that just north of 135 MPH is possible without a limiter since the maximum engine speed is 7000 RPM, but the fact that these things are biased toward ride comfort means that there's insufficient body control (for me, at least) to do sustained running above 100 MPH. I think that's the real reason GM won't let it run freely.

Note the engine speed - if the road is flat (or downhill) and there's a tailwind, then it would be around 3600 RPM since the transmission would stay in top gear with the torque converter fully locked. I usually only see that if the road speed is 100 MPH (exactly 3000 RPM) or less. BTW, while 100 MPH is easy on the nerves, it's hard on the wallet - about 14 MPG. That's why I spend most of my road time at 80 MPH or less; I've seen a best of just over 27 MPG at 70 MPH.

 

That's interesting. I've had my 15 terrain v6 to a little over 120.... Approaching 125. I had to slow down because of road conditions. However it was still pulling at those speeds albeit slowly. I think it is reasonable to assume they can do 130.

 

Did you do that with cruise control?

 

 

I did my 100 MPH runs with cruise, but it wasn't set for the picture. Cruise will not set at or above 115 MPH.

 

I neglected to add that while I have no problems with directional stability at those speeds, I was alarmed at how much the nose dived the first time I had to decelerate suddenly due to being cut off. If that problem could be fixed with some suspension parts, I would most certainly do it. I suppose it's good that there's no real aftermarket - that'll keep me down to speeds I can afford to travel.

Stiffer springs should help, but that heavy front end isn't helping matters.
I have the upgraded factory FE2 suspension.
I wouldn't say it's soft but some of my passengers have mentioned to me that they think it's on the stiff side for a stock SUV.

 

 

It is not how fast you can go, the most important thing is how soon you can stop the vehicle. 🤔

 

After spending more time with our Equinox and upgrading its brakes (with rotors and aggressive pads from EBC Brakes), I used HPTuners to eliminate the limiter on it last week because I 'needed' to see what it would do. I finally was able to get out today for a run after waiting for the velocity tax collectors to go back to sleep. I saw 138 MPH in one direction and 134 MPH in the opposite direction on a six-lane stretch of Interstate highway before running out of room (there was light traffic at the time that got heavier). Straight-line stability at those speeds is still surprisingly good, and the confidence that I've gained in it since my last post allowed me to trust it when running that quickly. It still doesn't make up for the cost, though; 135 MPH = 8 MPG (or about 170 miles of range on a full tank)! I'll post pictures when I'm able to do it with both of my eyes on the road and both hands on the wheel. In contrast, my last road trip was 24 MPG at 65 MPH into a 25 MPH headwind.

 

It's not a good idea to push it beyond what is required to pass. Even if you have high speed rated tires they better be in perfect condition and aired up correctly and evenly. If ANYTHING goes wrong at high speed you could die and maybe kill a bunch of other people. The Equinox is not designed to operate like a sports car.

 

I'd trust my 'nox at 130 today more than my old '68 GTO which I had up to that speed back in the '70s on those old, belted Polyglass tires.
I've had my snowmobile at 107 mph on GPS, I guess I'm a nutty old guy.

 

I applaud you can stop on a dime. You can fly over 130 mph without leaving the ground and I wish you well. Please don't come near me. I have been there and done that with my 95 Astro van on a secondary highway without a soul in sight. Nothing to brag about. When you get to my age then you will realize how smart you were moving those four tires at that speed. I am an nutty old guy too but I want to live until it is time for me to go, not someone else pushing me out. 🖖

 

In my 2005 (before I swapped the LNJ engine for the LX9), max speed I got was 105 MPH (170km/h).

Traveling from Puerto Vallarta back to Guadalajara.

 

"Just doesn't feel 300HP quick through 1st or 2nd gear."

The major contributor to the way our vehicles feel at lower speeds is their curb weight - approximately 6.5 seconds to 60 MPH says they do a decent job of overcoming that weight.

 

My 2013 V6 hit the speed limiter at190kmh and had a lot more left in it. Of course I live in a rural area of Canada and have a long flat stretch of road where it's wide open so no worries about deer or bears (furry or police).

Only did it once and have not had the urge to see what the 2022 will do. After all, it's just a lil 4 banger. It does cruise nicely at 130-140 kmh tho. Just takes longer to get there LOL
